# Unity 4.6: why Image object doesn't stretch all sides of canvas

I insert a canvas, after that, I insert an image at center. Then, I want to stretch this image over this canvas, so I choose last option as below:

But the image doesn't stretch to fit the canvas, as you see: (in fact, image object doesn't change anything)

Please tell me how to make this image stretches over the canvas.

thanks :)
